Abstract: A self wear compensating valve for controlling flow of a fluid
employs seals for sealing between relatively moving parts. In one
of the parts, an annular recess (10) is formed. A conformable sealing
member (8) is placed in the recess (10), and a spring (6) biased to expel the
conformable sealing member (8) and press it against a sealing surface (202)
on the other part is provided. An O-ring (18) placed on the outside of
the conformable sealing member (8) prevents leakage of fluid through
the recess (10) outside of the conformable sealing member (8). As the
conformable sealing member (8) is worn away, after many cycles of the
valve, the spring (6) continues to press it against the sealing
surface (202), while the O-ring (18) continues to prevent leakage of fluid
outside the conformable sealing member (8). A rotary valve suitable
for railroad brake applications is provided, which controls flow of
fluid from a supply (40) to the brake cylinder (60), and provides for exhaust
of fluid (70) from the brake cylinder. The valve has a supply port (40), a
delivery port (60) and an exhaust (70). In one position, the supply port (40) is
connected to the delivery port (60) through a passage in the rotor. In
another position, the delivery port (60) is connected to the exhaust
port (70) through a passage in the rotor (28). In a third position, the lap
position, all the ports are isolated from each other. Seals
prevent loss of fluid from the supply port (40) and from the delivery
port (60). A seal is also provided to prevent loss of fluid through the
exhaust port (70), when the delivery port (60) is not connected to the
exhaust port (70).

IPC: G01L23/22
Filed: 1996-07-02
Abstract: Gemäß der Erfindung kann eine Wechselstromzündanlage
auf zweifache Weise zur Ionenstrommessung verwendet
werden. Einerseits kann der primärseitige Schwingkreis
nach erfolgter Zündung so angesteuert werden, daß
primärseitig ein Wechselspannungssignal erzeugt wird,
dessen Amplitude hinreichend gering ist, um sekundärseitig
keinen Zündfunken herbeizuführen, jedoch zu
einem Wechselspannungssignal führt, das in Abhängigkeit
des Ionisationsgrades der Zündfunkenstrecke moduliert
wird und somit ein Meßsignal des Ionenstromes
darstellt. Andererseits wird bei Verwendung eines
Spartransformators als Zündspule die am primärseitigen
Ende anliegende Zwischenkreisspannung im Mittelspannungsbereich
von beispielsweise 180 V in Abhängigkeit
des Ionisationsgrades moduliert, so daß diese Versorgungsspannung
als Meßsignal dient.

IPC: H02K29/00
Filed: 1996-09-06
Abstract: A current magnitude sensing circuit for detecting a malfunction of a DC
brushless fan. The current magnitude sensing circuit detects drops in the current
magnitude in windings of a fan motor. Depending on the frequency of the current
drops in the fan current, the current magnitude sensing circuit outputs either a high
or a low voltage signal. The current magnitude sensing circuit operates by charging
a capacitor beyond a certain voltage and thereby providing a high fan fail output
signal when a fan is spinning too slowly for proper cooling of a device. Another
capacitor is charged at a different time constant for setting the fan fail output of the
current magnitude circuit low for indicating that the fan is spinning sufficiently fast.

Abstract: In calculating an electromagnetic field intensity by
a moment method, real and imaginary parts of a mutual
impedance, mutual admittance, and mutual reaction between
elements and of the elements themselves are approximated
by a sum of terms each with a frequency raised to a
power. The mutual impedances, etc. at a plurality of
sample frequencies are calculated using known
mathematical equations, and simultaneous equations
obtained by substituting the sample frequencies and the
mutual impedances at the respective sample frequencies
into an approximate equation are solved to calculate
approximation coefficients for the approximate equation.
Using the thus obtained approximate equations, the mutual
impedance, etc. at a designated frequency are calculated,
and substituted into simultaneous equations describing a
boundary condition for each element; by solving the
simultaneous equations, the electric current, equivalent
electric current, and equivalent magnetic current of each
element are calculated, from which the electromagnetic
field intensity is calculated.

Abstract: The system of the present invention allows a
customer to access a company computer system (14) via a
data network (12) and to request contact with a customer
service representative. The company computer
system (14) automatically selects a customer service
center and a customer service representative in
accordance with a set of selection criteria,
including customer preferences. A monitor (38), also
connected to the company computer system via the
data network, may choose to accept or to change the
selections made by the company computer system.
Once a customer service representative has been
selected, the company computer system causes a
telecommunication control device (40) to connect the
customer, the selected customer service
representative, and the monitor via a voice
network. If a monitor is not available, the
company computer system causes the
telecommunication control device to connect the
customer and the selected customer service
representative, and then records the communication
therebetween for future review by a monitor.
Optionally, the selected customer service
representative may initiate data communication with
the customer via the data network. The monitor may
readily monitor the data communication between the
customer and the customer service representative
via the data network.

Abstract: Laser light emitted from the wavelength-locked
GaN semiconductor laser is collimated through a collimation
lens, led through a polarization beam splitter and
a 1/4 wavelength plate, and converged by a focus lens so

medium. The signal light from the optical disk medium is
collimated by the focus lens, and has its polarization
direction turned by the 1/4 wavelength plate by 90°
relative to its polarization direction before being
returned from the optical disk medium. As a result, the
signal light is reflected from the polarization beam
splitter so as to be converged on the optical detector by
the focus lens.
